Started at one end of the sound, at the isthmus between the Calf of Man and the main Isle of Man. The broken wreck of the Clan McMaster lays at 15m deep.Drift is 3-4 Knots of tide!
Loop around the castle (45 min to 1 hour) in 10m of water. There is a very nice Kelp Forest and small caves. The must here is to play with the local seals.
The dive is to follow the base of the Iron Pier, in and out of the under-water structure. The marine life is great with a lot of crustaceans.The Dolphin few minutes from the end of the pier. This is a concrete structure, not a mammal!
